Bob,
Goods points .. but even without the concept of "pushing or pulling"
on the chassis at an angle ... suspension heights do not remain static
during normal operation. If the rear axle is does not run absolutely
parallel with the swingarm axis, (throughout it's complete orbit) ...
the magnitude of the deviation, (the direction it is pointing ...
other than absolutely straight ahead), will change as the rear
suspension compresses or is extended. It will infact cause the rear
wheel to steer the bike .. depending on the distance the axle happens
to be from the chassis ... This changing of direction .. no matter how
slight will cause the tail wag that will induce tank slapping head
shake ... When we stiffen everything up on the chassis ... we are only
moving the the chance to resonate up to a higher frequency, (a tighter
string plays a higher note).
IMHO of course ... Sooooo ... all this crap means is that I think that
offset is OK ... but pointing in any direction other than straight
ahead is not .... (and this would be true on any plane ...as a
"twisted" swingarm that pointed "straight ahead" at normal ride height
would not be doing so as soon as it moved up or down ... it has no
choice ... it's arc would not be true). OK .. let me have it !!
